The main difference between a mason jar and a kilner jar is the top. A kilner jar has a rubber-sealed screw top, while a mason jar has a disc-shaped metal lid and an outer metal part that screws around it.
Harriet should ask several senior citizens to evaluate whether her jar lid design is easier to use than a traditional jar lid.

Often, lids are made of metals which are great conductors of electromagnetic waves (including heat). When warm water is applied to a "difficult" lid, excitement of the atoms in the metal occurs (very slight) which causes a slight expansion. This expansion helps the lid to be moved from it's grip on the jar or bottle. This is also found in plastics. Although not through expansions. The heat from the warm water literally softens the plastic.
A jar lid is typically considered a screw or lever simple machine. The twisting motion used to tighten or loosen the lid acts similar to a screw, while the leverage from the lid helps to create a tighter seal on the jar.
Put in jar and screw on lid.Put the sauce in a jar then screw on the lid.
Yes, a jar lid can have a screw-on design to secure it tightly onto the jar. This type of lid is commonly used for sealing jars to keep the contents fresh and prevent leakage.
Screw
A type of simple machine found on the lid of a pickle jar is a screw. Turning the lid either tightens or loosens the screw, allowing you to open or close the jar.

A screw is typically found on the lid of a pickle jar, making it a type of simple machine known as an inclined plane wrapped around a cylinder. Turning the lid causes the screw to move, allowing the jar to open or close.

Yes. It is a screw action, which is a simple machine.
I use a glass jar with a screw on lid. It can be frozen and put into the microwave with the lid off to thaw. So, there are several advantages using the jar.
